155
156        * Mega patch merge to change the format of the object IDs to
157        loosen the dependency between the SCORE and the various APIs.
158        There was considerable work to simplify the object name management
159        and it appears that the name_table field is no longer needed.
160        This patch also includes the addition of the internal mutex
161        which is currently only used to protect some types of allocation
162        and deallocation.  This significantly can reduce context
163        switch latency under certain circumstances.  In particular,
164        some heap/region operations were O(n) and had dispatching
165        disabled.  This should help enormously.  With this merge,
166        the patch is not as clean as it should be.  In particular,
167        the documentation has not been modified to reflect the new object
168        ID layout, the IDs in the test screens are not updated, and
169        _Objects_Get_information needs to be a real routine not inlined.
170        As part of this patch a lot of MP code for thread/proxy blocking
171        was made conditional and cleaned up.

191
192        * include/rtems/score/thread.h, inline/rtems/score/thread.inl,
193        src/threaddispatch.c, src/threadinitialize.c:
194        Move the C library re-enterrant support directly into
195        the thread dispatch code. RTEMS needs libc and so requiring
196        libc to use a user extension with its overhead is not the best
197        solution. This patch lowers the overhead to 2 pointer moves.

201        * include/Makefile.am: Work-around to autoconf-2.53 adding PACKAGE_*
202        to autoheaders - sed out *PACKAGE* from cpuopts-tmp.h.

2042001-05-14      Till Straumann <strauman@slac.stanford.edu>
205
206        * src/threaddispatch.c, src/threadhandler.c: Per PR211 fix
207        saving/restoring floating point context.  The fpsave and fprestore
208        routines are only used in a executing context which _is_ fp and hence
209        has the FPU enabled. The current behavior required the FPU always to
210        be on which is very dangerous if lazy context switching is used. 
211        [Joel Note: Some ports explicitly enabled the FPU in the FP save and
212        restore routines to avoid this.]
213
214        The patch also makes sure (on powerpc only) that the FPU is disabled
215        for integer tasks. Note that this is crucial if deferred fp context
216        switching is used. Otherwise, fp context corruption may go undetected!
217        Also note that even tasks which merely push/pop FP registers to/from
218        the stack without modifying them still MUST be FP tasks - otherwise
219        (if lazy FP context switching is used), FP register corruption (of
220        other, FP, tasks may occur)!
221
222        Furthermore, (on PPC) by default, lazy FP context save/restore
223        is _disabled_.

227        * src/objectcomparenamestring.c: Fix typos.

230
231        * include/rtems/score/object.h, inline/rtems/score/object.inl,
232        src/objectcomparenamestring.c: Address PR81 that
233        reworked POSIX message queues to add a descriptor separate from
234        the underlying message queue.  This allows non-blocking to follow
235        the "open" not the underlying queue.   As part of debugging this
236        it became clear that _Objects_Compare_name_string was broken
237        and a simple version using strncmp() was substituted.

253        user extension is created after a task is started it may not know it.

388        * inline/rtems/score/Makefile.am: Remove.
389        * inline/Makefile.am: Handle subdirs, require automake-1.5.
390        * Makefile.am: require automake-1.5
391
3922001-09-28      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
393
394        * include/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.
395        * include/rtems/Makefile.am: Use 'PREINSTALL_FILES ='.
396        * inline/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.
397        * macros/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.
398
3992001-09-27      Eric Norum <eric.norum@usask.ca>
400
401        * src/threadhandler.c: Now process C++ global constructors
402        (_init) as part of the first task execution not in BSP space.
403        This depends on the toolset defining USE_INIT_FINI so you
404        have to have the right toolset version.
405
4062001-09-23      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
407
408        * include/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.
409        * include/rtems/Makefile.am: Use 'PREINSTALL_FILES ='.
410        * inline/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.
411        * macros/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.
412
4132001-08-30      Joel Sherrill <joel@OARcorp.com>
414
415        *  src/coremutex.c, src/coremutexseize.c, src/coremutexsurrender.c,
416        inline/rtems/score/coremutex.inl: The per thread field resource_count
417        should only be manipulated when a mutex is priority ceiling or
418        priority inherit.  This was reported by Chris Johns <ccj@acm.org>
419        who also noticed that the use of switches for all disciplines
420        generated less efficient code than using explicit tests for the one
421        or two cases we were really interested in.  Further review of his
422        modifications made it apparent that the "isa" methods to test mutex
423        discipline were not being used so this modification was swept into
424        the code as well.
425
4262001-08-30      Joel Sherrill <joel@OARcorp.com>
427
428        * src/coremutexseize.c: Add missing code for proper handling
429        of nesting acquisitions.  This only impacts building with
430        inlines disabled on the source with the "fast mutex" optimizations.
431        This was post the 4.5 branch and did not impact released versions.
432
4332001-08-16      Joel Sherrill <joel@OARcorp.com>
434
435        * src/coremutexsurrender.c: Use holder thread not executing
436        thread because even though they may and often are the same
437        it is not guaranteed unless the proper attribute is set.
438
4392001-08-16      Joel Sherrill <joel@OARcorp.com>
440
441        * include/rtems/score/coremsg.h, src/coremsgsubmit.c: Add a new
442        return status to account for blocking sends.  Otherwise, the
443        caller will think that the returned message status will have
444        the ultimate results of the operation.  If the send times out,
445        the final status will be in the return_code of the thread.
446
4472001-08-09      Joel Sherrill <joel@OARcorp.com>
448
449        * include/rtems/score/coremsg.h, inline/rtems/score/coremsg.inl,
450        src/coremsgsubmit.c: Unblocking message queue operations should
451        NOT use _Thread_Executing for return status since it is permissible
452        to invoke message send operations from an ISR.  This was reported
453        by Suvrat Gupta <suvrat@utstar.com>.
454
4552000-05-25      Sergei Organov <osv@javad.ru>
456
457        * macros/rtems/score/coresem.inl, inline/rtems/score/coresem.inl:
458        Cut and paste problem incorrectly enabled interrupts twice with
459        the first time being too early.
460
4612001-05-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
462
463        * include/rtems/score/.cvsignore: Add stamp-h, cpuopts.h,
464        cpuopts.h.in, cpuopts-tmp.h.
465
4662001-02-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
467
468        * include/rtems/Makefile.am, include/rtems/score/Makefile.am,
469        inline/rtems/score/Makefile.am, macros/rtems/score/Makefile.am
470        Apply include_*HEADERS instead of H_FILES.
471
4722001-01-29      Joel Sherrill <joel@OARcorp.com>
473
474        * src/objectextendinformation.c: Added include of string.h to
475        eliminate warning.
476
4772001-01-08      Joel Sherrill <joel@OARcorp.com>
478
479        * src/threadinitialize.c: Fix my bad hack of Ralf's fp_area
480        warning removal patch. :(
481
4822001-01-08      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
483
484        * src/threadinitialize.c: Removed warning.
485
4862001-01-03      Joel Sherrill <joel@OARcorp.com>
487
488        * src/isr.c: Modify to properly dereference _ISR_Vector_table
489        now that it is dynamically allocated.
490
4912000-12-19      Joel Sherrill <joel@OARcorp.com>
492
493        * src/isr.c: Allocate the _ISR_Vector_table all the time not just when
494        we are allocating an interrupt stack.
495
4962000-12-13      Joel Sherrill <joel@OARcorp.com>
497
498        * include/rtems/score/isr.h, src/isr.c: Allocate it from the
499        workspace rather than explicitly declaring it.  This allows
500        the size to be a non-constant from the perspective of score/cpu.
501
5022000-12-01      Joel Sherrill <joel@OARcorp.com>
503
504        * macros/rtems/score/coresem.inl: Removed comments since convention
505        calls for comments to be in inline versin.
506        * macros/rtems/score/object.inl (Objects_Get_local_object): Fixed
507        style to use _ prefix on variable names and use parentheses.
508        * macros/rtems/score/object.inl (_Objects_Namespace_remove): Added.
509
5102000-11-30      Joel Sherrill <joel@OARcorp.com>
511
512        * General effort to make things compile with macros not inlines
513        * inline/rtems/score/coremutex.inl: Added comment indicating
514        for macros there is another copy of
515        _CORE_mutex_Seize_interrupt_trylock() in src/coremutexseize.c.
516        * src/coremutexseize.c: Added body of
517        _CORE_mutex_Seize_interrupt_trylock() for macro case.
518        * macros/rtems/score/coremutex.inl: Added prototype for
519        _CORE_mutex_Seize_interrupt_trylock() since there is a real
520        body when macros are enabled.
521        * macros/rtems/score/coresem.inl: Added macro implementation of
522        _CORE_semaphore_Seize_isr_disable.
523        * macros/score/Makefile.am: Fixed typos.
524        * rtems/score/address.inl: Correct macro implementation of
525        _Addresses_Is_aligned() so it would compile.
526        * macros/rtems/score/coremsg.inl: Added closing parentheses.
527       
5282000-11-28      Chris Johns <ccj@acm.org>
529
530        * src/heapallocate.c: Do not allow the size to overflow when
531        adjusting it.  A test allocated a stack of -1 (~0). This
532        actually resulted in a stack being allocated but with a
533        size of 0xb. The allocator did not test the size to see if
534        it rolled through 0 and so allowed the allocation to happen, the
535        thread to get created. The task crashed as you would expect.
536
5372000-11-02      Joel Sherrill <joel@OARcorp.com>
538
539        * include/rtems/system.h: Use proper conditional (RTEMS_POSIX_API)
540        so prototypes for POSIX_MP_NOT_IMPLEMENTED(), POSIX_NOT_IMPLEMENTED(),
541        POSIX_BOTTOM_REACHED() are actually included.
542
5432000-11-02      Joel Sherrill <joel@OARcorp.com>
544
545        * include/rtems/system.h: Add prototypes for POSIX_MP_NOT_IMPLEMENTED(),
546        POSIX_NOT_IMPLEMENTED(), POSIX_BOTTOM_REACHED() removed from newlib.
547
5482000-10-18      Nick Simon <Nick.SIMON@syntegra.bt.co.uk>
549
550        * src/heapgetinfo.c, include/rtems/score/heap.h, src/Makefile.am:
551        Added _Heap_Get_information() and information control block.
552        * src/heapgetinfo.c: New file.
553
5542000-09-25      Joel Sherrill <joel@OARcorp.com>
555
556        * rtems/system.h: Switched a29k and hppa1.1 to using cpuopts.h not
557        targopts.h to reduce dependency on BSP.
558
5592000-09-20      Joel Sherrill <joel@OARcorp.com>
560
561        * src/objectgetbyindex.c: Do not enable dispatching on an
562        error path it was not disabled on.
563
5642000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
565
566        * src/Makefile.am: Include compile.am.
567
5682000-08-30      Joel Sherrill <joel@OARcorp.com>
569
570        * Many files: Moved posix/include/rtems/posix/seterr.h to
571        score/include/rtems/seterr.h so it would be available within
572        all APIs.
573
5742000-08-17      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
575
576        * include/rtems/system.h: Include cpuopts.h for __i386__.
577
5782000-08-10      Joel Sherrill <joel@OARcorp.com>
579
580        * ChangeLog: New file.
